As an RV owner, you know how important it is to have a reliable power source while on the road. One of the most important components of your RV’s electrical system is the automatic transfer switch, which allows you to switch between your RV’s generator and shore power seamlessly. In this article, we will discuss the wiring diagram for an RV automatic transfer switch, including the components involved, the wiring process, and some FAQs that will help you troubleshoot any issues that may arise.
Components
The automatic transfer switch (ATS) is a device that is designed to automatically switch the power source of a load between two sources. In an RV, the two sources of power are the onboard generator and shore power. The ATS is typically installed near the electrical panel and is connected to the generator, shore power, and electrical panel.
The ATS contains several components, including:
- Relays: These are the switches that allow power to flow between the generator and shore power.
- Control board: This is the brain of the ATS and controls the relays based on the power input and output.
- Sensing wires: These wires monitor the power input and output and tell the control board when to switch between the generator and shore power.
Wiring Process
Wiring an RV automatic transfer switch can be a bit complicated, but with the right tools and knowledge, it’s a job that can be done by most experienced RV owners. Here’s a step-by-step guide on how to wire your ATS:
- Turn off all power to your RV.
- Locate the electrical panel and disconnect all wires from it.
- Mount the ATS near the electrical panel and connect the incoming generator wires to the generator input terminals on the ATS.
- Connect the incoming shore power wires to the shore power input terminals on the ATS.
- Connect the output wires from the ATS to the electrical panel.
- Connect the sensing wires to the appropriate terminals on the ATS and to the control board.
- Test the ATS to ensure that it is working properly.
FAQs
Q: What should I do if my RV automatic transfer switch is not working?
A: The first thing you should do is check the power source to ensure that it is working properly. If the power source is working, then you should check the wiring to make sure that all connections are secure and that there are no loose wires. If everything looks good, then you may need to replace the ATS.
Q: Can I wire my own RV automatic transfer switch?
A: If you have experience with electrical wiring, then you can wire your own ATS. However, if you are unsure about any part of the process, it’s always best to consult a professional.
Q: How do I know if my RV has an automatic transfer switch?
A: Most modern RVs come with an automatic transfer switch installed, but if you’re not sure, you can check the owner’s manual or contact the manufacturer.
Q: What is the difference between an automatic transfer switch and a manual transfer switch?
A: The main difference between an automatic transfer switch and a manual transfer switch is that the former switches between power sources automatically, while the latter requires manual intervention to switch between sources.
